Protecting the Communication Path via a
Device Certificate
This machine can protect its communication path and establish encrypted communications using SSL/
TLS, IPsec, S/MIME, or IEEE 802.1X. It can also protect PDFs by means of a PDF or PDF/A digital

To use these functions, it is necessary to create and install a device certificate for the machine in

before they expire.

XP SP3 or later is required to connect the device using Internet Explorer 6.0.
